I find the motion sensing and gps tracking to be the creepiest. Using motion sensing they can know when you put your phone down and pick it up, if it was screen down or face up, and knows when you are walking, running, driving, etc. Combined with GPS it can be used to pretty accurately judge when you wake up, where you go, and how you get there. Lots of apps also don't "close" when you swipe it away, they continue running in the background, so if you have the setting "only collect data when using the app" it will still collect data until you close it in the background or force stop it.

Paying for premium is fine, but premium users letting Youtube off the hook for their corporate greed is annoying. If YT ran reasonable ads like they used to in the olden days I wouldn't use an adblocker. Don't even get me started on their garbage search, a multi billion dollar company can and should do better. Then of course there's the fiasco of their demonetization system, and rules that apply to some but not others. Simply put they don't deserve to be paid for premium, if their grinch heart grows and they decide to do better as a company I'd honestly pay for premium.
Been using Windows since XP, watched it get worse with every iteration while getting a shiny new exterior. Was finally forced from Windows 7 to Windows 10 a few years ago and the day Windows tries to foist 11 on me is the day I go fully down the Linux rabbit hole.
Discord went the way of Skype, it's just a bloated fustercluck now. I don't use it often, just once a month or so to keep up with a group of old friends, and every time I fire it up it has a new update bringing features I don't give a rats ass about.
